I think the neatest part of that show was the Camera Obscura.

Have you ever been in a real camera obscura? We went to the one in
Edinburgh this summer - it's SO cool. After the demonstration, they
turned this red light on, and I took a photo with a fisheye at ISO 1000.

I think the one in the program was more impressive in a way.

It had no lens!!


That's rather the point of a camera obscura.


I'm pretty sure it isn't.
"camera obscura" == "dark chamber"


Ok, you're going to have to elaborate a little. What is there in the
phrase 'dark chamber' that says a camera obscura is constructed with a
lens?

I'm loath to quote wikipedia but too lazy to do anything else: "The
principle of the camera obscura can be demonstrated with a rudimentary
type, just a box (which may be room-size) with a hole in one side".
